XM20C64

XM20C64 64K XM20C64 High Speed AUTOSTORE™ NOVRAM 8K x 8 FEATURES DESCRIPTION The XM20C64 is a high speed nonvolatile RAM Module. It is comprised of four Xicor X20C16 high speed NOVRAMs, a high speed decoder and decoupling capacitors mounted on a co-fired multilayered Ceramic substrate. The XM20C64 is configured 8K x 8 and is fully decoded. The module is a 28-lead DIP conforming to the industry standard pinout for SRAMs. The XM20C64 fully supports the AUTOSTORE feature, providing hands-off automatic storing of RAM data into E2PROM when VCC falls below the AUTOSTORE threshold. The XM20C64 is a highly reliable memory component, supporting unlimited writes to RAM, a minimum 1,000,000 store cycles and a minimum 100 year data retention. High Speed: tAA = 55ns NO Batteries!!
